Long life and low power RGBW OLED displays

摘要

To provide a red, green, blue and white (RGBW) OLED that may realize extended lifetime and/or reduced power consumption.SOLUTION: A first device is provided that includes a first light source that has at least one organic light emitting device, and the organic light emitting device may emit near-white light having a correlated color temperature (CCT) less than 6504K. The first device also has a plurality of pixels comprising a first sub-pixel, and the first sub-pixel has a color filter in optical communication with the first light source that passes light having a peak wavelength between 400 and 500 nm. A second sub-pixel has a color filter in optical communication with the first light source that passes light having a peak wavelength between 500 and 580 nm. A third sub-pixel has a color filter in optical communication with the first light source that passes light having a peak wavelength between 580 and 700 nm. A fourth sub-pixel emits near-white light that may have a CCT less than 6504K.SELECTED DRAWING: Figure 3
